Let us consider the following scenario. Water is pumped to high pressure, but the water then faces a fork in the pipe. Two pipes lead back to the pump: large pipe L and small pipe S. Since the water can flow through either pipe, the pipes are said to be in parallel. Since this is so, the overall flow of water that enters the system before the fork is equal to the sum of the flows through L and S.(adsbygoogle = window.adsbygoogle || []).push({});

What can be stated about the drop in potential energy (per unit mass or volume) of water traveling through either pipe?

a. The drop is greater for pipe L.

b. The drop is greater for pipe S.

c. The drop is the same for both pipes.

Is the answer a? Since there is a a greater flow of water in the large pipe, there is a greater mass of water for potential energy? Is this right at all? If not, please explain the correct choice to me.

Thanks.
